I have a 94 Blaster, 61x, with a Riva pipe, TDR waterbox, and Boyesen reeds. JetManiac and I have been trying to get it back on the water all summer with nothing but frustration.
So far I've replaced the coil, CDI, and have run 3 different stators (2 used replacements from JM). The symptoms I'm describing below have occurred with 3 different stators. The CDI and coil I replaced earlier in the summer when the B1 didn't want to rev while in my garage. The CDI and coil seemed to solve this.
When it's cold and I drop it in the water, I'll get about 5-7 minutes of ride time before it starts to act up. During those first few minutes, it runs great and responds to all throttle inputs. I've had a similar issue in the past with my SJ, and a new stator solved it. Once the B1 is warm, anything more than about 1/3 throttle and it won't respond but it won't quite die. Just doesn't want to rev. It will idle fine and always starts right back up.
If you let it it sit for an hour or so to cool off, then try again, you might get 30 seconds to a minute before it starts to not respond to any throttle inputs. If you keep trying, more than about 1/4 throttle will actually cause it to die. Again, it always starts right back up and idles fine.
Fuel tank check valve is in working order, allows air into tank but not out.
I've stood in waist deep water and let it ride around in circles with the hood up around me while I checked for exhaust leaks and all seems good.
JetManic and I are stumped what to try at this point.
Fuel selector valve? Bypass the fuel selector? Carb rebuild?
Since it seem so temperature dependent, we keep thinking it's electrical.
I'd like to get it back on the water for a few more weekends this summer, but I'm already in the process of acquiring the needed parts for a 1200 swap.
